What is the rule to rotate 90 degrees clockwise?
Rule: If we rotate a shape 90 degrees clockwise, each point of the given shape should change from (x,y) to (y,x), showing the rotated shape. Let’s look at some examples to understand how to rotate a shape 90 degrees clockwise.
How to rotate 90 degrees clockwise?
Answer: To rotate a shape 90 degrees clockwise around a point, each point (x, y) is rotated by (y, x). It helps to visually understand a 90 degree clockwise rotation around a point. Therefore, each point must be rotated and find new coordinates.
What is the rule for rotating 90 degrees counterclockwise about the origin?
rotation about the origin
If you rotate the point 90 degrees counterclockwise about the origin, our point A(x,y) becomes A(y,x). In other words, swap x and y and make y negative.
How to rotate 90 degrees clockwise?
Answer: To rotate a shape 90 degrees clockwise around a point, each point (x, y) is rotated by (y, x). It helps to visually understand a 90 degree clockwise rotation around a point. Therefore, each point must be rotated and find new coordinates.
What is the formula to rotate 90 degrees clockwise?
The rule for a 90° rotation about the origin is: (x, y) → (−y, x).
What is the rule to rotate 90 degrees clockwise around the origin?
If the point is rotated 90° clockwise around the origin, point M(h,k) will take the image of M(k,h). Therefore, the new position of the point M(2, 3) becomes M(3, 2).
How to rotate a point 90 degrees?
The rule for a 90° rotation about the origin is: (x, y) → (−y, x).
